To all "whom it may concern Be it known that I, ELMEP. T. GALLEY, a citizen of the United States, residing at Huntington Park, in the county of I os Angeles and State of California, have 1nvented certain new and useful Improvements in Reversible Windows, of which the following is a specification.

This invention relates to that class of reversible windows in which the window sash is pivoted to the substile on its edges and the invention relates more particularly to means for connecting the substile and sash edge pivotally and rigidly.

An object of the invention is to provlde a reversible window having a tight solid lock joint between the substile and the edge of the sash when the sash is in register \vlth the substile and not free to turn on its pivot; also to make novel provision whereby the substiles are frictionally held in the pulley stiles when the sash is turned on its pivot and incidentally to provide means whereby the sash is frictionally held so .as to not move too freely on the pivot when unlocked from the substile.

A further object is to provide against sticking of the parts from swelling of the substile or sash.

A further object is to make cheap, simple and strong provision .for locking the sash and substiles together.

The accompanying drawings illustrate the invention.

F 1g. 2 1s a fra gmental elevation of the window shown in Fig. 1, the sash being turned on its plv'ot, portions of the pulley stiles belng broken away for clearness of illustration. F 1g. 3 1s a fragmental elevation of some of the parts in Fig. 1, portions being broken away to ex pose to view the pivoting device.

Fig. 5 is a fragmental lower end view of the window showing the substile and the sash stile locked together. Fig. 6 is a fragmental elevation in section on line :12, Fig. 5. Fig. 7 is av cross-section of the stiles and the window pivot on line 00 Figs. 1 and 3 cutting through the pivot of the window. Fig. 8 is a perspective view of the cleft pivot piece of one of the pivots, detached. Fig. 9 is a perspective view of the grooved pivot bearing member of said pivot, detached. Fig. 10 is a perspective of the assembled pivot, detached.

The pulley stiles 1 of the window frame may be of any usual construction and there is slidably mounted therein the reversible window of any desired character having the sash stiles or edges 2 and substiles or supplemental stiles 3 and also having a cleft pivot member 4 between each of the sash stiles and substiles, and locking means movable into and out of the \l-shaped cleft 5 of said pivot member. The pivot member 4 is fixed to the sash stile 2, there being one of such pieces on each stile of the sash and each piece is provided with a projecting conical pivot stud 6 into which a cleft 7 extends a short distance so that at the sides of said pivot stud there are two parallel members 8 provided with countersunk holes 9 through which screws 10 are passed to fix said members to the edge of the sash stile.

The pivot members 4 are fixed to opposite sash stiles with the pivot studs 6 in axial alinemecnt with each other and outside of each pivot member is provided a grooved pivot bearing member 11 having a conical pivot bearing 12 to receive and journal the pivot stud 6 and also provided with a V shaped groove 13 registering with the cleft 5 in the pivot member. Said pivot bearing member is provided with screw holes 14 through which screws 15 are passed to fasten the pivot bearing member to the substiles 3. Said pivot stud 6 forms at its outer end a cam 16 which may be in the form' of a centrally located wedge, the outer narrower edge of which extends diametrically across the-end oi the stud, and said edge seats in a longitudinal tapered seat 17 in the bearing member 11 which is bridgedover at its outer ends excepting at a centrally circular orifice 18 through which a pin 19 from the center of the pivot stud 6 extends far enough-to receive a helical coil spring 20 and washer 21 and suitable means holding the washer and spring in place. Said means may be a screw screwed into the end of the pin or may be a rivet 22 swaged over to form the head of the pin as indicated at 23.

The pivot bearing member 11 may be provided externally with a circular seat 24 to receive the inner large end of the collapsible spiral spring 20. The tension of said spring normally holds the cleft pivot member a and the grooved pivotal piece or bearing member 11 yielclingly though tightly together. The meeting faces 25 of said pivot members 1 and 11 are flush with the stiles to which they are respectively secured, so that the meeting faces of said stiles are held in contact when the groove and cleft register with one another and the Wedge 16 is in its seat 17. lVhen the sash is turned on its pivot the wedge 16 is thrust out of its seat 17 with a cam-like action, thus spreading the substiles 3 away from the edges 2 of the sash and from one another.

There is provided plenty of play between the substiles 3 and the bottom of the rabbets I 26 of the pulley stiles 1 to allow the sash to freely move up and down whenever the faces of the substiles and sash edges are in contact with each other but such play is less than the play between the sash edges and the substiles that is caused by the cam action of the wedge 16 when the sash is brought to transverse position; and the substiles are provided between their ends with a gain 27, there being left at each end of the substile a flat foot or projection 28 engaging the pulley stile and firmly held thereagainst by the force of the cam, the intermediate portion 29 of the substile being sufliciently resilient to accommodate the thrust of the cams 16 after contact between said feet and pulley styles has been effected. By this means the frictional engaging faces of the substiles 3 with the pulley stiles 1 are of sufficient extent to prevent slippage and yet there is suflicient resiliency of the substiles to prevent excessive friction so that rotation of the sash on its pivots may be accomplished with comparative ease combined with firm fixation of the window in the pulley stiles. This action tends to give a slight permanent bow to the meeting faces 25 of the substiles 3 so that, when the sash is again brought into register with the substiles in closing the window, the free ends of the substiles will fit snugly against the ends of the sash edges 2 opposite the feet 28.

In order to positivly lock the sash and the substiles 3 together in closed position and in perfect registration with one another and also to prevent lapping or looseness, and to positively close the joint between the sash and the substiles, tongues 30 are seated in longitudinal conjoined grooves 31, 32 in the sash and substiles respectively, said grooves 31 1n the sash being sufiiciently deep to en tirely accommodate the tongues and said grooves 32 registering with the mouths of the grooves 31. Furthermore, for the purpose of avoiding sticking and to elfect positive closure of the joint, each tongue 30 and the grooves 31, 32 are wedge shaped or V- shaped and are of narrowing cross-section toward the adjacent edges of the substile and sash, and the limbs of the V-shaped tongue are joined at their convergent portions, and the tongue at its outer edges is conformed to the groove in the substile so that when the tongue is fully extended it fits tightly against the inclined sides of and wedgedly into said substile groove 32 and also against the inclined sides of the sash stile groove 31. By making the tongue 30 and grooves 31, 32 V-shaped, it is clear that cutting away of the stiles and substiles for said grooves will be minimized so that the sash will not be weakened and that the tongue will be of maximum strength and owing to its V-shape will readily pass into the groove 32 and into the cleft 7 and groove 13, even though the sash stiles and substiles be not in perfect alinement.

Any suitable means may be employed for shifting the tongues 30 edgewise in the grooves to lock and to release the sash relative to the substile. A form of such means that is deemed very desirable consists in providing the upper end of the tongue 30 with a projection or thumb-piece that extends over a notch 34: cut conjointly in the upper inner corner of each sash and the adjacent corner of each substile 3 to allow the thumb or any instrument to engage with said thumbpieee which preferably is flush with the upper face of the sash; and there are seated in the sash stiles stop means which may be pins or screws 35 passing through the groove 31 and forming a connection arranged by suitable means to cause the tongue to shift edgewise into and out of the substile groove 32 as the tongue is moved endwise, which means will now be described.

In one form of construction detailed in Fig. 6 the tongue 30 is bent from sheet metal, the sides of the tongue being formed of the spaced apart edges of such sheet metal and being provided with correspondingly slanted slots 36 which engage the pins 35 and slide thereon to shift the tongue edgewise as stated. In this form the projection 33 on the tongue is made by bending over and flattening together the end of the tongue sides.

In practice the window sash may be raised and lowered in the usual manner, the window cords and pullevs not being shown as thev form no part of this invention.

When it is desired to open the windows pieces 33 will be operated to raise the tongues 30 to force them inward out of engagement with the grooves 3:2 and pressure will be brought to bear against the upper or lower edge of the window sash to cause the sash stiles 2 to turn relative to the substiles 3, thereby to cause the cams 16 to ride up the slanting sides of the wedge-shaped seat 17 until the ends of said cam rest against the bottom of the bearing 12, thus wedging the substiles 3 away from one another and against the pulley stiles 1 and springing the middle portions 29 of the substiles away from one another and flexing said middle portions into engagement with the window frame, as shown in Fig. 2, to supplement the clamping action of the upper and lower projections 28. From this it will be seen that the resiliency of the springs 20 tends to pull the sash stiles and substiles toward one another and that the resiliency of said springs is supplemented by the resiliency of the substiles 3 which also act to relatively force the sash stiles and substiles toward one another; and that, when the window sash is closed, perfectly weather tight joints are established between the sash stiles and substiles; and that notwithstanding perfect tightness of the oints when the window is closed, the window may be operated with great ease to open and the window sash and substiles will be separated while opening and closing so that their adjacent edges will not chafe and bind against one another and consequently cause diiiiculty of operation and marring of said edges.

It is clear from the foregoing that whether or not the sashes are properly counterbalanced by being connected to one another or by counterweights, both of which constructions are well understood in the art and therefore are not herein shown, the cams 16 afford means to force the substiles 8 tightly against the bottoms of the rabbets 26 so as to securely hold the sash to whatever position it has been adjusted up and down relative to the pulley stiles 1; and furthermore it is clear that in the case of comparatively small windows, the counterbalancing means can be dispensed with altogether and the sash can be held in adjusted position by the thrusting force of the cams alone. When the studs 6 are forced from their seats 17 by turning of the sash stiles 2, the outer ends of said studs are forced. into frictional engagement with the end thrust walls 40 of the bearing members by the force of the springs 20 and also by the compression force of the yielding, resilient and bendably mounted substiles 3 so as to yieldingly hold the sash stiles from turning on the pivots or studs 6. It is seen from the fore oing that owing to the provision of the flat feet 28 when the substiles are bowed outward by turning of the sash on its pivots said feet will befirmly held against the frame stiles, and that when the sash is alined with the frame stiles there is no more friction between the substiles and frame than in the ordinary sliding sash; furthermore, by having the flat feet at the ends of the substiles and bowing the substiles outward it is clear that the tendency will be for the substiles to assume a more or less permanent bowing outward, thus causing the end portions of the substiles to closely hug the sash stiles and insure against there being any open joints between said ends and sash stiles, thus preventing the entrance of rain, winds and dust.

I claim 1. In combination, window frame stiles, a sash having stiles and substiles pivoted together, said substiles being resilient and provided at their ends with flat feet, and means operable by turning the sash on the pivots to bow the substiles outward and force the feet into frictional engagement with the frame stiles.

A window sash having a stile and substile, a pivotal member mounted in the edge of the stile and provided with a V-shaped cleft, a bearing member for said pivot member mounted in the edge of the substile and having a V-shaped groove to register with the cleft, a V-shaped tongue, and means to shift said tongue edgewise to and from the cleft and groove.

3. A window sash having a stile and sub stile, a pivot member mounted in the edge of the stile and provided with a cleft, said pivot member having a stud into which said cleft extends and having a wedge-shaped cam at the outer end of the stud and having a pin projecting from the center of the stud, a bearing member mounted in the edge of the substile and provided with a circular pivot bearing to journal the stud and also provided with a groove registering with the cleft, said bearing member being provided with a tapered seat for the cam and being bridged over at its outer end excepting at a centrally circular orifice accommodating the pin, a coil spring seated against the bearing member and surrounding the pin, means on the outer end of the pin to hold the spring, and means insertible into the cleft and groove to prevent turning of the pivotal piece.
